A cheaper way to upgrade our lenses
Not that I recommend taking them apart for this:
This is the world's blackest material - and it's now available as a spray paint Quote:
The blacker / more non-reflective the side surfaces are, the less that light scatter will interfere with your desired image. Andrew |

Re: A cheaper way to upgrade our lenses
But it has to be heated to around 100 Celsius to undergo the reaction to produce the carbon nanotubes that absorb the light. Not sure if they recommend many lenses getting that hot.
Might be great material for a backdrop, light spill won't matter as the reflectivity is so low. Last edited by Andrew Hood; April 6th, 2016 at 04:47 AM. Reason: Looking at the wrong temp - Vanta black can handle up to 300 |

Re: A cheaper way to upgrade our lenses
I thought it was still unbuyable by normal mortals at this point?
You guys have seen the Chicago bean is now coated in this, right? If not, Google it. It's... Just wow.

Re: A cheaper way to upgrade our lenses
You don't need to make the whole lens this hot, just the lens casing as it would be applied to the inside of this to eliminate internal spill.
